Show HN: Git Guide - The open source travel guide on GitHub ActionsHello HN!This is my first open source project, and I’m excited (and a little nervous) to share it with you.I love traveling, but I’ve lost trust in traditional review sites. Between SEO spam, bots, and paid 5-star ratings, finding genuine recommendations has become a noise-filtering exercise. I wanted a curated list where the "noise" of anonymous internet crowds is replaced by a transparent commit history.Git Guide is an experiment in building a community-curated travel directory without a traditional backend or database.* No Database: The "database" is just folders of Markdown files (countries/Italy/Rome/Eat/best_pizza.md). * No Servers: It runs entirely on GitHub Actions. * IssueOps: Data isn't entered via a custom form; it's entered via GitHub Issues with YAML templates.How it works: 1. A user opens an Issue to propose a place. 2. The community votes using GitHub reactions (/). 3. Once a threshold is met (currently testing with net 100 votes) and a moderator approves, a Python scrip
IMAGEEarly universe dark matter born red hot before coolingLos Angeles CA (SPX) Jan 14, 2026 Researchers at the University of Minnesota Twin Cities and Universite Paris-Saclay report that dark matter in the early universe may have started out moving at nearly the speed of light, challenging the long held assumption that it had to be born cold and slow. Their work suggests that the universe's dominant unseen matter component could have been incredibly hot at birth yet still cooled suffic

They report entanglement across 48 dimensions with more than 17 000 distinct topological signatures, providing a large alphabet for encodin
IMAGEShow HN: Turn Your Git Commits into TweetsOP here. I've been trying to "build in public" recently, but I found that switching context from VS Code to Twitter/X just to write "Fixed a race condition" felt like friction. I often ended up posting nothing because translating code-diffs to human-readable text takes more mental energy than fixing the bug.I built Git to Tweet to automate this loop.How it works:It hooks into your GitHub repo (via OAuth).It pulls the metadata and diff summaries of your recent commits.It passes the diff through a specifically tuned prompt (to avoid generic "AI slop") that extracts the intent of the code change rather than just listing file names.It generates a draft that you can edit before posting.The Tech Stack:Frontend: React + Framer Motion (spent way too much time on the "terminal" animations you see on the landing page).Backend: Node.js/Supabase.LLM: Currently testing models to see which is best at understanding code context without hallucinating features.The landing page includes an interactive s
IMAGEWhen 5G networks bolster satellite navigationTokyo, Japan (SPX) Dec 26, 2025 Finding accurate positions in dense urban areas remains difficult for satellite-based navigation systems, where high-rise buildings and signal blockages can cause large errors or complete loss of service. A recent study outlines a deeply integrated positioning method that combines commercial 5G New Radio (NR) signals with Global Navigation Satellite Systems (GNSS) to address these issues. By rei
IMAGEWind-Sculpted Landscapes: Investigating the Martian Megaripple 'Hazyview'Pasadena CA (SPX) Dec 26, 2025 While much of Perseverance's work focuses on ancient rocks that record Mars' long-lost rivers and lakes, megaripples offer a rare opportunity to examine processes that are still shaping the surface today. Megaripples are sand ripples up to 2 meters (about 6.5 feet) tall that are mainly built and modified by wind. However, when water in the atmosphere interacts with dust on the ripple surface, a
